Abstract
The utility model discloses an antiskid protection device for a machine tool, and relates to the field of a mechanical equipment manufacturing technology. The antiskid protection device comprises a vertical screw rod vertical to the interior of a vertical screw rod seat; a friction plate and a movable ring are sequentially sheathed on an extending part of the vertical screw rod extending out of the vertical screw rod seat; a star wheel is arranged between the upper section of the movable ring and the vertical screw rod; an axial thrust ball bearing is arranged between the lower section of the movable ring and the vertical screw rod; a disc spring is connected with the end surface of the axial thrust ball bearing in a pressing way; the other end surface of the disc spring is provided with an adjusting pad; and the adjusting pad is connected with the disc spring in a pressing way by a lock nut sheathed on the thread of the end of the extending part of the vertical screw rod. The antiskid protection device for the machine tool solves the problems that after mechanical balance damage failure or motor brake failure, operators are injured, the accuracy of the machine tool is influenced, a cutter is damaged, the surface of a workpiece is scratched, and the like since a vertical part of a boring and milling machine slides down, so that the economic loss can be caused.
Description
Technical field
The utility model relates to plant equipment manufacturing technology field, especially a kind of in, the large-sized numerical control milling-boring machine is vertical uses anti-skidding protection mechanism.
Background technology
Current domestic manufacture, sale and use be numerical control mill boring machine or the supporting vertical Lift Part of machining center, have following defect: 1, only have vertical lifting motor dead electricity band-type brake, lifting motor dead electricity band-type brake can make vertical parts because of Gravitational sliding after losing efficacy; 2, only have vertical mechanical type counterweight balance, after the chain of weight or steel wire rope fatigue fracture, vertical parts are because of Gravitational sliding; 3, only has the hydraulic accumulator balance, because the inefficacy of accumulator balance or pipeline leak produce vertical parts because of Gravitational sliding.The existence of these defects, can make the vertical parts of milling-boring machine down cause operating personnel injured during landing in accident, and machine tool accuracy is impaired, and cutter is destroyed, and surface of the work such as is bruised at the accident, causes unnecessary economic loss.
The utility model content
Problem to be solved in the utility model is to provide a kind of lathe anti-skid protector; it can solve after the vertical parts of milling-boring machine damage to lose efficacy because of mechanical balance or motor internal contracting brake lost efficacy; because of gravity down landing may cause operating personnel injured; machine tool accuracy is impaired; destroyed and the surface of the work of cutter is bruised etc., the problem of economic loss.
In order to address the above problem, the technical solution of the utility model is: this lathe anti-skid protector comprises the vertical screw mandrel be contained in vertical screw rodb base; The extension that described vertical screw mandrel stretches out described vertical screw rodb base is set with wearing piece and moving-coil successively; Between described moving-coil epimere and described vertical screw mandrel, be provided with star-wheel, be provided with axial ball bearing between described moving-coil hypomere and described vertical screw mandrel; Described axial ball bearing end face is crimped with disk spring, and described disk spring other end is provided with adjusting pad, and described adjusting pad compresses and is connected with described disk spring by the locking nut be enclosed within on described vertical screw mandrel extension ends screw.
In technique scheme, more specifically scheme can be: the described described star-wheel of described vertical screw mandrel that is enclosed within is by flat key and described vertical screw mandrel interlock; In described star-wheel, be provided with the fore-set of linking springs, described fore-set withstands the roller be located between described star-wheel and described moving-coil.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
When the gravity produced when 1, the vertical parts of the utility model milling-boring machine glide drives vertical screw mandrel rotation, just overcome and stop vertical screw mandrel rotation to reach the purpose that vertical mechanism does not glide to frictional force with mechanical adjustable anti-skidding institutional adjustment.
2, solve because of the vertical parts of milling-boring machine, damage because of mechanical balance lost efficacy, motor internal contracting brake lost efficacy because of gravity down landing may cause operating personnel injured, machine tool accuracy is impaired, cutter is destroyed, surface of the work is bruised etc., the function of economic loss,
3, described anti-slipping mechanism can be applied on multiple Digit Control Machine Tool.
4, can improve the reliability of lathe, good cost performance.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cutaway view in Fig. 1.
Number in the figure means: 1, wearing piece; 2, star-wheel; 3, axial ball bearing; 4, moving-coil; 5, disk spring; 6, adjusting pad; 7, locking nut; 8, flat key; 9, vertical screw mandrel; 10, spring; 11, fore-set; 12, roller; 13, vertical screw rodb base.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The lathe anti-skid protector of Fig. 1 and Fig. 2, comprise the vertical screw mandrel 9 be contained in vertical screw rodb base 13, and the extension that vertical screw mandrel 9 stretches out vertical screw rodb base 13 is set with wearing piece 1 and moving-coil 4 successively; Between moving-coil 4 epimeres and vertical screw mandrel 9, be provided with star-wheel, star-wheel 2 is enclosed within on vertical screw mandrel 9, by flat key 8 and vertical screw mandrel 9 interlocks; In star-wheel 2, be provided with the fore-set 11 of linking springs 10, fore-set 11 withstands the roller 12 be located between star-wheel 2 and moving-coil 4.Between moving-coil 4 hypomeres and vertical screw mandrel 9, be provided with the axial ball bearing 3 be enclosed within on vertical screw mandrel 9; Axial ball bearing 3 end faces are crimped with disk spring 5, and disk spring 5 other ends are provided with adjusting pad 6, and adjusting pad 6 compresses and is connected with disk spring 5 by the locking nut 7 be enclosed within on vertical screw mandrel 9 extension ends screws.
Operation principle of the present utility model is: when the vertical parts of boring and milling machine lost efficacy because of accident, because driving vertical screw mandrel 9, gravity is rotated counterclockwise, as scheme A-A cut open the institute look, spring 10 pushes away fore-set 11 and makes the little spatial movement of roller 12 toward star-wheel 2, increase star-wheel 2, frictional force between roller 12 and moving-coil 4, vertical screw mandrel 9 drives moving-coil 4 and is rotated counterclockwise, and moving-coil 4 produces the friction motion with wearing piece 1; By adjusting 7 pairs of adjusting pads 6 of locking nut, the thrust of disk spring 5 and axial ball bearing 3, thereby the friction of adjustment moving-coil 4 and wearing piece 1, reach and overcome the purpose that vertical parts glide; Avoid the vertical parts of milling-boring machine down to cause operating personnel injured during landing in accident, machine tool accuracy is impaired, and cutter is destroyed, and surface of the work such as is bruised at the accident, thereby avoids unnecessary economic loss.
